First: Gary, you keep mentioning that there are "still issues with PATH"
and all of these solutions only take care of part of the problem.
What are these other issues? The only issues I know of are the Python
sys.path issue, and fallout from various attempted fixes.
As for the solutions on the table:
The current system is for waf to just dump the python libraries in /usr/
(in theory it might put it somewhere else, but this is where it has been
observed to go) if it encounters a problem. This is unacceptable. This
*will* be removed before 1.1.
The former system was for waf to install in the correct location, but
for the python libraries to be inaccessible on some distros. The problem
was handled by suggesting to the user that they add the path to their
PYTHONPATH. This is not good either, but in comparison with the current
FHS violation it is acceptable. If no one can agree on a better solution
this is what will be shipped in 1.1.
For alternate fixes we have rlaager's (!615) fix. The tradeoffs I see are:
bad: the entire concept is a hideous violation of good import
practices and generally all that is right and proper
good: it Just Works(tm) for any install path you throw at it
The second fix is .pth files:
bad: it will have to go under /usr/ (or equivalent depending on
exact path)
bad: apparently breaks inter-version seals between different copies
of NTP. But this is true of any distro with /usr/local/
good: it doesn't bypass python versioning <--- This is a Huge Win
over telling users to use PYTHONPATH
good: it works for everyone on a system
good: despite technically violating FHS it does so in a
non-colliding manner
neutral: I'll bet that this doesn't solve the specific variant of
the problem that I've encountered (a weird variant)
IMHO if we end up defaulting to the old method we should suggest the
user create a .pth file instead of PYTHONPATH. PYTHONPATH is a mess for
this kind of thing.
